Aeshna clepsydra (Mottled Darner)Among the state’s rarest Aeshna species. Known from four sites: Lily Pond and Sadawga Lake in Windham County, Wells in Rutland County (probably Lake St. Catharine) and Winona Lake in Addision County. Like most other Aeshna, prefers marshes and ponds with emergent vegetation. Pond Lily is typical at its sites. Shows some affinity for lakes with fringing bogs. Our only Aeshna species with a “mottled” – rather than striped – thoracic pattern.
